" Role of Diffusion Weighted Image in the Diagnosis and Follow up of Breast Cancer"

Most of the lesions that occur in the breast are benign lesions. It is important to recognize benign lesions and distinguish them from breast cancer. Nowadays sonomammography still represents the primary imaging modality utilized for breast cancer screening and diagnosis. Breast MRI has become an important tool for breast cancer detection and characterization.Contrast enhanced MRI(CE-MRI) is currently the most sensitive detection technique for diagnosis of breast cancer.Diffusion weighted imaging provides micro-structural informations regadrding the diffusion of the water molecules in the tissue cellularity and tissue structure by using the quantitive analysis with the apparent diffusion coefficient (ADC) values. Using Diffusion weighted imaging (DWI) combined to MRI is helpful to distinguish malignant versus benign breast lesions and it also may reduce the number of unnecessarily breast biopsies.
